The Marshalltown MXS Plasterer's Finishing Trowel is great for concrete or plaster. It has an aluminium alloy mounting which is very light, but as strong as steel. The flexible blade is of the highest grade spring stainless steel, tempered, ground and polished and is fastened to the mounting with ten hard steel rivets. The curved DuraSoft handle is held firmly by a nut and washer. The blade is made from stainless steel which is easier to clean. These trowels do not corrode and are therefore much longer lasting.
